The essence of the solution lies in proposals for improving the efficiency of frequency estimation at the input signal synchronization stage, which is presented on the example of a satellite telecommunication control system and distance learning. Namely, the analysis of modern satellite telecommunications systems was carried out and the features that affect the effectiveness of carrier frequency estimation and input signal synchronization were determined. The main inconsistencies are the low energy of the input signal receiving channel, significant signal frequency uncertainty, and the presence of \"neighboring channels\" receiving the input signal. It was determined that satellite communication systems during data transmission work in the mode with multi-station access in the variant of operation with frequency division of channels, which can receive data packets in the mode of multiple access or when providing a data reception channel on demand. At the same time, the operation of telecommunications systems can proceed both in continuous and in batch modes of receiving the input signal. It is considered that coherent processing of the input signal is carried out in demodulators of satellite telecommunications and interference-resistant coding is used.\u0000To solve the task of estimating the carrier frequency of the input signal in coherent demodulators of modern satellite telecommunications, considering the above-defined inconsistencies and features, the article proposes a methodical approach. The essence of this approach is to determine the potential boundary of variances of the obtained estimates of the carrier frequency and to develop algorithms for estimating the carrier frequency of the input signal separately for continuous and batch modes of input data transmission based on the fast Fourier transform.\u0000Keywords: Frequency, signal, uncertainty, carrier, estimation.","PeriodicalId":107886,"journal":{"name":"PIRETC-Proceeding of The International Research Education & Training Centre","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129076331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The low-count issue is the main source of these issues. Sparse prediction is more likely to be chosen as the solution as sparse technology is employed more frequently. I suggest a brand-new sparse prior technique in this research to process low quality PET reconstructed pictures. Two dictionaries (D1 for low-resolution PET images and D2 for high-resolution PET images) are trained from plenty of actual PET image patches in the proposed approach. The sparse representation for each patch of the input PET picture is then obtained using D1. Finally, D2 is used to create a high-resolution PET image from this sparse representation. The results of the studies show that the suggested strategy has superior effects that improve image resolution and detail recovery that are stable. In terms of root mean square error, this technique performs better quantitatively than older methods (RMSE). The suggested method offers a fresh and effective way to enhance the image quality of PET reconstructions. The back projection technique was created for magnetic resonance imaging (MRI) picture reconstruction of under sampled data and has been used to denoise dynamic PET images.\u0000Keywords: PET imaging, data acquisition, artifacts, resolution, information technologies.","PeriodicalId":107886,"journal":{"name":"PIRETC-Proceeding of The International Research Education & Training Centre","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122231727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Improved rail transport can also help attract foreign direct investment, increase participation in global production networks and the scale of related trade in manufactured goods, and diversify exports. Improved rail infrastructure will increase global competitiveness and spur economic development. In addition, improved rail infrastructure will help regional cooperation and integration through improved connectivity between people, goods and services. The operation is carried out by a railway company, providing transport between train stations or freight customer facilities. Power is provided by locomotives which either draw electric power from a railway electrification system or produce their own power, usually by diesel engines or, historically, steam engines. Most tracks are accompanied by a signalling system. Railways are a safe land transport system when compared to other forms of transport. Railway transport is capable of high levels of passenger and cargo utilisation and energy efficiency but is often less flexible and more capital-intensive than road transport, when lower traffic levels are considered.

A modulation characteristic measuring and classification system for classifying a discreet signal that includes a preprocessor, stage measuring system and modulation classifier. Preprocessor detects impulse begins and finishes, determines impulse time, and changes the discreet signal into digital signals. The stage measuring system determines short chip counts, long chip counts, stage jump magnitudes, number of stage states, and polynomial coefficients for stage modulation of the discreet signal. Modulation classifier identifies modulation type on base of measurements using both rules-based and similarity-based classification methods. The lack of educational-oriented software in the IMS field leads to a more challenging learning curve resulting in a drop in student motivation. Software integrated with GNE is purposed to minimize the overwhelming feeling in students in the IMS field by simultaneously providing understandable execution order for the machine. An application consisting of GNE with the addition of custom node architecture and their interaction logic is built to conduct laboratory work using this software. Executed laboratory work result shows that having GNE integrated into the software can significantly impact visual understanding, leading to higher motivation and interest in the subject in students.\u0000Keywords: Node, Graphical Editor, GPIOS, Information measurement system.","PeriodicalId":107886,"journal":{"name":"PIRETC-Proceeding of The International Research Education & Training Centre","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114494107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But an important destabilizing factor among these reasons, of course, is the temperature of the molten raw material and its stability over the entire production cycle. Due to the inaccurate setting of the temperature of the raw material and its change during the production process, the raw material can be more or less liquid or viscous, which directly affects the quality of the pipe. Due to the temperature error, it is difficult to accurately determine the wall thickness of a plastic pipe. When the pipe is stretched to the required thickness, intramolecular deformations of the pipes may occur, which can have a deplorable effect on the operation of the pipes in the future. Therefore, all pipe manufacturers pay special attention to temperature control.
